Understand the Problem
The question is asking about feedback inhibition in metabolic pathways and provides multiple choice options related to this concept. The respondent has selected option 'A' as the answer, indicating that it involves the end product inhibiting the first committed step in the pathway.
Answer
The end product inhibiting the first committed step.
Feedback inhibition in metabolic pathways typically involves the end product inhibiting the first committed step.
Answer for screen readers
Feedback inhibition in metabolic pathways typically involves the end product inhibiting the first committed step.
More Information
This inhibition prevents the accumulation of unnecessary intermediates and conserves cellular resources. It often involves allosteric regulation, where the end product binds to an enzyme at a site other than the active site.
Tips
A common mistake is confusing feedback inhibition with other types of inhibition like competitive or noncompetitive inhibition.
